To all whom it may concern:

Be it known that I, HERBERT H. HULL, a citizen of the United States, anda resident of the city of Lakewood, in the county of Cuyahoga, State ofOhio, have invented certain new and useful Improvements in Side-SealClosures, of which the following is a specification.-

Thls invention relates broadly to closures and more specifically to aside seal.

The principal object of the present invention is to provide a side sealof a character wherein the sealing operation brings into play forcesacting angularly to the Wall of the container whereby a compressiblegasket is forcibly seated against the side of the container.

Another object of the present invention is to provide a side sealwherein there is a .minimum distortion of metal in order to ob viate thedestruction of lacquer on the caps.

A still further object of the present invention is to provide a capwhich when sealed against a closure presents a'bead wherein the, excessof metal in the sealing operation is flowed outwardly toward the edge ofthe bead, and wherein substantially a smooth annular rim is presentedabove the sealing bead.

A still further object of the present invention is to provide a capadapted to be sealed to form a side seal, and wherein the excess metalin sealing is taken care of witlhout formation of grooves in thefinished sea O Other and further objects of the present invention willin part be obvious and will in part be pointed out hereinafter in thespecification following by reference to the accompanying drawings 1nwhich like parts are represented by like characters throughout theseveral figures thereof.

Figure 1 is a sectional detail view-illustrating the cap in accordancewith this invention prior to the sealing operation.

Fig. 2 is a detail View showing the relation of parts immediately afterthe seal is completed and illustrating the action of the a complete upthe excess metal formed during the sealing operation. Such grooves to amore or less extent tend to break the lacquer skin Also in the type ofclosure comprising this invention the sealing action takes place underangular forces so that the gasket is subjected to what might be termed atoggle action, which very tightly compresses the gasket against the sidewall of the container.

Referring now more particularly to the drawings, it will be noted thatthe cap comprises a cover portion 1 which preferably includes adownwardly depending flange 2, an outwardly extending wall 4 which maybe slightly depressed, as illustrated at 5 in Fig. 1. This outwardlyextending wall is continued in the form of an angularly disposed skirt 6which is of slightly less diameter at the bottom than at the top. Thisdiameter enables the cap to securely and conveniently carry a suitablegasket member 7 which before the seal is completed passes freely overthe side wall of the con- .talner 8 which is preferably a glassreceptacle of the tumbler type and may be formed with a cylindricalportion 9 adjacent the mouth thereof.

In the sealing operation the bead is compressed between an upper chuckl0 and a lower chuck 11 in such manner as to straighten the outwardlyextending wall f and to incline the skirt 6 to an inclination ofpreferably about twenty-five (25) degrees relatively to the cylindricalside wall 9. Under this action it is to be noted that the gasket 7 iscompressed between the out- Wardly extending wall 4 and the skirt 6somewhat after the action of a toggle member. This forces the gasket 7very tightly against the cylindrical side wall 9, and the excess metalof the sealing operation is disposed ofby being flowed into the rib oredge 12 of the finished closure.

Having thus described my invention what I claim is ii.
